Description
Technical field
The utility model discussion be a kind of sampler of industrial combustion coal burning boiler, particularly can have the sampler of filtration, dehumidification function simultaneously.
Technical background
Sampler is that on-line analysis system contains moisture and has SO at the high dust of flow process gas sample, height
2, Nox, NH
3Under the bad working environments condition Deng corrosive gas, provide the industrial gas sample of gas analyzer, finish the necessary device of gas ingredients analytic function.The gas sample is sampled by stopple coupon, just can enter analytical instrument through pretreatment unit udst separation, removal moisture.The sampler of traditional both at home and abroad at present on-line analysis system configuration generally only disposes porous filter, filters the dust that contains in the gas sample.Industry coal-boilers such as power station since combustion process in flue gas in except that dust is arranged, also contain the moisture of suitable concentration, they can with the SO in the gas sample
2, Nox, NH
3Produce stronger corrosive liquids and aerosol Deng the water-soluble gas reaction, not only analytic system is produced than heavy corrosion, and increased the analytical error of gas ingredients.In addition, traditional sampler is taked constant temperature companion heat (130 ℃ ~ 160 ℃), makes gas temperature be higher than about 30 ℃ of dewpoint temperatures, prevents that condensate water from separating out.This trace pipe device just needs the dress temperature sensor every 4 ~ 5 meters, with this control the hot gas piping temperature of companion (temperature fluctuation＜5 ℃=.Moreover trace pipe apparatus structure complexity, cost costliness, work are unreliable.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of sampler of the gentle sample dehumidification function of collection dust-filtering that can use under industrial combustion coal burning boiler bad working environments.
The utility model adopts following technical scheme to finish above-mentioned task.Sampler comprises stopple coupon, companion heat filter, Thermal packer, vortex-induced cooler, and industrial sample gas connects industrial analysis instrument after by stopple coupon, companion's heat filter, Thermal packer, vortex-induced cooler.The Thermal packer top has a hole and connects back-flushing valve.The vortex-induced cooler comprises the cylinder that housing tube, sample inflator, three concentrics of cooling cylinder are placed, and the housing tube is at outermost, and cooling cylinder is interior; The sample inflator is connected with pipe 1, pipe 2 respectively on vertical plane with cooling cylinder, and cooling cylinder is the tube of sealing, and housing tube, sample inflator are the tubes of both ends open.Housing tube one end is fixed on the Thermal packer, is connected with the Thermal packer concentric with the up-to-date style inflator, and the other end of housing tube, sample inflator is connected with case, has the outlet of sample gas on the case; The top of housing tube has the compressed air inlet, and the below has the cold wind escape hole, and sample inflator below has condensed water discharge outlet, and it passes the housing tube and is connected with the condensate water draining valve.Pressurized air connects Thermal packer through the compressed air inlet of refrigeration operation valve body contact body tube through back-flushing valve.
In order to reduce gas sample and condensate water duration of contact, the gas sample is during by the vortex-induced cooler, and the inwall that is in contact with it is made special " hydrophobic " with tetrafluoroethene (Teflon) and handled and makes that condensate water is very fast discharges from drainpipe, minimizing SO
2, Nox, NH
3Water-soluble Deng gas sample composition, reduce analytical error." Teflon " material not only has " hydrophobic " property, also has strong corrosion resistance, and the protection connection removes warm device inwall and is not corroded.
The opening and closing action of condensate water draining valve 4, refrigeration operation valve 5, back-flushing valve 6 is controlled by the PLC programming controller.
The utility model sampler utilizes compressed-air actuated strong vortex to produce the quench cooled effects of reduced temperature, and the moisture rapid condensation is separated out, and feeds analytical instrument through the dry gas sample of dehydration.This device can not only filter most of flue dust and reduce the constant temperature companion's heat request and the pretreatment unit cost of oxygen cathete, and guarantees SO
2, Nox, NH
3Can ignore etc. water-soluble influence, reach and analyze purpose accurately, and improve system's resistance to corrosion and system reliability level.
